OLIVER Webb was again left cursing his luck after failing to finish the Le Mans 24-hour race at the weekend.

An engine failure forced the retirement of ByKolles Racing Team's entry, bringing to an early end a World Endurance Championship round blighted by problems.

"It's obviously a huge disappointment," said the 25-year-old afterwards.

"I'm gutted we couldn't get a result."

The German outfit's LMP1 class machine's power plant caught fire during free practice on Wednesday, leaving their mechanics to spend the next 48 hours repairing the damage before qualifying.

Forced to start the race from the grid's 27th row, their woes continued when smoke filtered from the engine before the lights went out.

After pitting to fix the problem, Pierre Kaffer joined the race a lap down.

The car continued to lose power for the next 16 hours, leaving them unable to compete with fellow LMP1 privateers Rebellion Racing.

Their rivals endured mechanical setbacks too, prompting them to slip down the order, but Webb - sharing driving duty with Kaffer and Simon Trummer - was unable to capitalise after the engine on ByKolles' machine expired in the early hours.

"I'm certain good things are coming from us," added the Briton.

"We should look at the positives, and we were fastest in class in wet conditions.

"The team made a huge effort to make us competitive."

ByKolles sit third in the FIA Endurance Trophy team standings after three meetings.

The series resumes with a six-hour race at the Nurburgring next month.
